Carbamate Pesticide Analysis Columns

Overview

Carbamate Pesticide Analysis ColumnsCarbamate Pesticide Analysis Columns

Pickering Laboratories carbamate columns are guaranteed to produce the separation of carbamate residues, specified by EPA 531.1, EPA 531.2 and AOAC 985.23 methods.

Post-column conditions for pesticide analysis:

Reagent 1: Hydrolysis reagent CB130 or CB130.2 Reagent 2: 100 mg of OPA, 2 g Thiofluor™ in 950 mL of CB910 Reactor 1: 100 °C, 0.5 mL Reactor 2: ambient. 0.1 mL Reagents flow rate: 0.3 mL/min

Detection:

Fluorometer: λex 330 nm, λem 465 nm

The recommended gradient conditions are subject to change without notice. This may happen because of lot specific changes in the columns, or improvements in the overall method.

The recommended gradient for the column will always be included in the column package, and it supersedes the information in this catalog.
